46 Claims.

This invention relates to printing machines of the type wherein variable printing devicesfare sequentially passed through the machine and it is particularly directed to a selector mechanism for controlling the printing operations of the machine in order that only determined or selected of the printing devices will be used in printing operations.

Printing devices of the character used in the machine of the foregoing type are arranged in a predetermined sequence and when not in use are filed in the drawers of suitable cabinets. The machine embodies a magazine into which the devices in any one of the storage drawers may be introduced and also embodies a mechanism for successively withdrawing the devices from the magazine to pass them through selecting and printing positions in a step-by-step manner to a packer mechanism that directs the devices into a galley wherein they are collected in the same sequence .asthat in which they were .arranged in the drawer when introducedintothe magazine. The

salient object of the invention is to determine which of the printing devices so passed through the machine are tolbe used in printing operations.

The embodiment of the invention disclosed herein is one which maybe used in the printing of tax bills and the like, but it is to be understood that the disclosure forsuoh purpose is merely exemplary and is not to beinterpreted as the only manner in which the invention may be utilized.

Printing devices .used in the printing of tax bills are often arranged in groups, this being necessitated by the length of the legal descriptions of the parcels of real-property to be taxed, for sometimes allof the legal description cannot be conveniently arranged on a single printing device and in such instances legal description is arranged on ,as many printing devices as is necessary. The first of such a group of printing devices has thereon the name and address of the party being taxed and other pertinent information and all or a part of the legal description, and these are known as lead'printing devices. The subsequent or follower printing devices of the group do not have the name and address thereon but have only as much of the legal description as can .be conveniently arranged thereon, When the device is used in the printing of tax bills it is sometimes desirable that only certain of the-printing devices or groups of printing devices be used'in printing operations, as for example, certain persons will pay their taxes annually while others will pay their taxes semi-annually and manifestly when the printing, devices are beingnsed to print tax (Cl. MIL-58) not only single successive sequentially arranged printing devices may be selected for printing operations but also to provide a selector wherein printing devices arranged in groups may be se lected so that not only one but all of the printing devices of a group may be used or notbeused in a printing operation. 7

The legal descriptionof the parcels of property are so worded that an entire parcel is described thereby, but under certain circumstances such a parcel of property may be divided, that is, a, portion or portions thereof may be sold or otherwise disposed of and when this is done, it is desirable that the legal description be changed so that each portion will have an independent legal description. This, of course, necessitates changing the legal description on the printing devices, and it is common to make these changes at the time the property is divided, and therefore new printing devices willbe introduced into the sequentially arranged groups of printing devices which will change the sequence, and it is necessary that the newly inserted printing devices not be used in a printing operation until a new sequence, including them, is established. It is therefore a further object of this invention to provide a selector which will determine such newly added printing devices in order that printing operations will not be performed therefrom bythe machine.

Further objects are to provide a variable selector that will regulate the printing operations from variable members on the printing devices; to provide a selector wherein avariation of the determinedoperation or a special operation may be brought about easily; to provide a selector that will normally regulate operation of the printing means of the machine and which will maintain the timed relation of the various elements of the machine; to provide a selector wherein the arrangement of the detecting portion may be varied expeditiously; and to provide a selector mechanism which may be manually positioned to permit repetitious operation of'the machine.

For the purpose of describing my invention I have shown a printing machine which embodies a main frame 26 having'at the upper end thereof a bed Zionwhich the printing operations are performed. A bracket 28 on the main frame provides a bearing 29 in which a shaft 32 is jour naled and rotatably mounted on this shaft is a flywheel 30. Power is transmitted to the flywheel from a suitable source by a belt arranged in the groove 3i in the flywheel, or in any other approved manner. A clutch structure 33 interconnects the flywheel and shaft 32. Mounted on the shaft 32 is another clutch structure 55%,- described morefully hereinafter, which connects the spur gear 35 to the shaft 32. The spur gear 35 meshes with a spur gear 36 rotatably mounted on the shaft 3'! and joined to a spur gear to by a collar 38. The spur gear 39 meshes with the pinion 48 fixed on the shaft 4! (Fig. ll) extended to the front of the machine into a gear housing 32.

Fixed on the shaft ii in the gearhousing are three gears 43, 44 and 2-5 (Fig. 8) of progressively greater diameter. Another shaft 53' extends into the gear housing through a bushing 50 and carried by this shaft are gears 46, 4'! and 48 meshed with the gears 43, '44 and 45, respectively. The gears it, ii and 48, are rotatablymounted on a bushing 49 on the shaft 63. In the bearing portions of the gears 46, iii and 38, restingonthe bushing 19, are pockets it, 4? and 43 and in the bushing is an opening 5i, and by properly positioning the gears the pockets and opening may be arranged in intercommunication. In the opening 51 is a tumbler 52 (Fig. 9) in the nature of a pin having relieved sections defining rounded portions 53', 54 and 55,axially spaced from each other and circumferentially disposed, each cornprising one-third of the diameter of the tumbler. On the outer end of the tumbler is a knob 55 having an opening 5? therein, and the outer end of which is closed, in any desired manner, to confine a spring 58 in the opening. The spring acts on a ball 59 to force ittoward the disc es. The disc 66 cooperates with a flange 69 on the bush ing 49 and the gears 45, s1 and 48 are confined between the disc 69 and the flange 49. The disc is connected to the shaft 63 by a plate 5 I, which has an elongated opening therein receiving a similarly shaped portion on the shaft, the plate being connected to the disc by bolts 52. On the face of the knob 55 is suitable indicia which is respectively aligned with the rounded portions 53, 54 and 55. In the face of the disc 6B are three sockets in which the ball 59 may be selectively seated. By turning the knob to move a portion of the indicia thereon into vertical position a certain one of the rounded portions on the tumbler will project beyond the opening 5| and will seat in one of the pockets, depending upon which of the rounded portions is in the described projected position, the ball 59 seating in a socket to retain the parts in this position. In the present instance the portion 54 is disposed in the pocket ll and therefore the gear (ii is connected to the shaft 63', and in this manner a selected one of the gears 46, 4? or 48 may be connected to said shaft 63. The ratio between the gears .5 and 8 is 1 to l; the ratio between the gears 44 and 31 is 2 to 1; and the ratio between the gears 43 and 46 is 3 to 1. Therefore, the shaft 5! may be either arranged to rotate at the same speed as the shaft 63, or it may be arranged to rotate either twice or three times as rapidly depending upon which of the gears is connected to the shaft 63.

A shaft 63 is journaled in a bearing 64 (Fig. 11) and in a bearing 65 adjacent the compound gear train '58. The end of the shaft 63 extending from the end of the housing 42 is journaled in a bearing 66 adjacent the compound gear train, which serves to reduce the speed of the shaft 63 so that this shaft will rotate in determined relation to the rotation of the shaft 32. On the shaft 83 is a bevel gear 69 which meshes with a bevel gear 10 on the cam shaft H which extends longitudinally of the machine and which is journaled in a suitable manner.

On the inner end of the shaft 32 is a bevel gear 12 meshed with a bevel gear 13 on the platen operating shaft 14. When the clutch 33 connects the flywheel 30 to the shaft 32, this shaft and consequently the shaft M is rotated, but the other shafts, above described. are not rotated until the clutch 3 3 is engaged. The utility of this arrangement is set forth hereinafter.

The machine includes as a part of the printing means thereof a platen P, and this platen is operated by means on the platen operating shaft i4 and'is carried by the platen arm H. The platen arm Ti includes a leg 76 (Fig. 4) pivotally mounted on a lug 75 on the bed 21. Branch arms E8 and 79 are provided on the platen arm and are extended on opposite sides of the shaft is, and rotatably mounted thereon are rollers 80 and 81 respectively engaging conjugated cams B2 and 83 fixed on a sleeve I80 disposed about the shaft M. Extending forwardly from the arm ii is the platen or stamper arm 84 which carries the platen Rand as the sleeve I00 rotates with the shaft M- the rises on the cams 32 and 83 impart a rocking movement to the platen arm about the pivotal mounting thereof on the lug 75 to move the platen toward and away from printing position to perform the printing operation.

The selector forming the subject matter of this invention controls the reciprocation of the platen and the printing device feed in a manner to be set forth. In my co-pending application, Serial No. 497,439, filed in the United States Patent Office on November 22, 1930 the manner in which a sheet, such as a tax bill, is moved into the printing position to be operated on by the platen P is fully described. In my co-pending application, Serial No. 497,440, filed in the United States Patent Office on November 22, 1930 I described the manner in which the sheets are stored and supplied tothe sheet positioning mechanism. Herein, the selector is disclosed as it is used to control the printing operations on sheets supplied and moved in the manner described in these co-pending applications, but it is to be understood that this is merely illustrative and thereiore this disclosure is not to be taken as a lirhita tion of the invention to such use, for the selector is capable of being used in many other ways.

Fixed on the platen operating shaft M is-an eccentric 12 (Fig. 3) surrounded by a band l3 embodying a portion it carrying a plunger IS on which a collar I6 is secured by the pin H. The plunger 15 is extended through a sleeve l8 carried by an arm on the printing device feed rocker 19 that is pivotally mounted at 2|] on the bed'ZT. The printing device feed rocker includes an arm 2| (Fig. 5) having a pawl 22 pivotally mounted at the outer end thereof including a recessed nose portion 29" successively engageable with the pins 24 on the sprocket 25 mounted on the bed 21 and about which-the printing device feeding chain is directed. On' this chain are pawls fii or other suitable devices of the charactcr well understood in the art, which engage the edges of the printing devices to sequentially move these devices through the printing device guideway 85 in one direction.

A latch 81 having a shoulder 88 thereon normally engaging the collar I6 is pivotally mount-' ed at 89. When the printing device feed rocker is to be operated the shoulder 88 on the latch 81 is engaged with the upper edge of the collar is (Figs..3,' 6 and '1) by the actionoi thespring- 81 and the rotative movement imparted to the eccentric I2 is translated to reciprocate the plunger l5; As the plunger and printing device feed rocker will. be interconnected a, rocking movement will be imparted to the rocker and the pawl 22 thereon will. successively engage the pins 24 to impart a step-by-step movement to the sprocket 25 to thereby bring about a step by-step advancement of the printing devices through the guideway 85. i F

The detecting portions of the selecting mechanism of my improved device are operated from the printing device feed rocker l9. The detecting portions include the casting 99 pivotally mount ed on the bed 21 at 9:! and having a bar 92 (Fig. 5) fixed thereto engage-able by the roller 93 on the rocker I9. When. the rocker i9 is motivated in the manner previously set forth the roller 93 engages the bar 92 and pivots the casting 90 about the pivotal mounting 9k thereof. As best shown in Fig. 6, the selector bar 94 is' pivotally mounted at on the casting 90 and includes-an arm 9| normally urged into engagement with the pin 92 by the spring 93: extended between a spring anchor on. the bar 94 and a spring anchor 96 depending from the casting 99. In the selector bar 94 a plurality of openings 91 are provided in which the headed pins 98 are inserted, the heads of said pins resting on the upper surjiace of the bar 94 and. being held in engagement the rivet Hi3 fixed in. the bar 9 in such a manner that one end of the plate'99is secured below the head of the rivet, and a screw W4 is; passed through the slot to I into the bar 94 and by tightening or loosening this screw the plate 99 may be secured or detached, and when detached it may be removed and therefore the pins 98 may be positioned or removed from the openings 91' the first in the order of passagethrough the machine. on each of the printing devices areniembers T (Fig. 7), in the form of detachable tabs in the disclosure, and the printing deVices as is well understood in. the art, have. retention The means thereon for attaching tabs thereto. tabs may be disposed at diiierent positions along the edge of the device, this edgebeing disposed rearwardly as the printing devicespass through the guideway 88, it being understood thatihe printing devices are introduced into a magazine M in a predetermined sequential order and that the printing device feed arrangement successively withdraws printing devices from the magazinc and passes'them through the guideway first into selecting position and theninto printing position, afterwhich the devices are passed to a suitable packer mechanism which introduces the devices into a galley G (Fig. 2) wherein they are collected and stored in the same sequential order as that in which'they were arranged when introduced into the magazine A selector mechanism is often so arranged so printing operations will be performed on printing devices having the tabs located in predetermined positions, these positions being determined by the positions of the pins 98 in the openings 9?, the location of the openings 91 corresponding to the positions of the retention means on the print-f ing devices. The selector mechanism may also be arranged to render the platen, inoperative when the detecting portions of the selectcr'engage tabs located in predetermined positions, and when the device is arrangedin this manner it is said to' be in skip position while, when it is arranged in the first described manner, it is said to be arranged in print position. 7

Should the casting 99 be moved in the manner described the selector bar 94 will also move, and in the event the tabs on the printing device E95 are not positioned similarly to the location of the pins 98 the selector bar 96 and the casting 99 willmove as a unit to the limit of the movement in the direction in which the casting 953 is moved'by the action of the roller 93. However, should thetabs T be positioned similar to the location of the pins 98 the movement of the selector bar with the casting will be interrupted and therefore this barwill be pivoted, about its mounting 95, relative to the casting 99. Connected to the selector bar. 94 is an arm It"! (Fig. 7) having the lower end of a link m9 pivotally connected thereto at I99. When the selector bar 94 moves with the casting 99 the centers of the pivotal mountings 9! and H39 are coincident, but when the selector bar 94 is stopped by engagement of the pins with tabs the coincidence of these centers is altered and the link i 9 i", moved downwardly. V

The selector mechanism includes a bracket i !9 depending from the housing ll l surrounding the platen operating and. the selector mechanisms. A bell crank II 2 is pivotally mounted at II 3 on the bracket H9 and eccentrically journaled in the outer end of the arm I I4 of the bell crank I I2 is a pin I I5 having a knob I9 secured thereto.

The upper end of the link I38 is connected to the eccentric pin II5. The eccentric pin is so mounted that it may be disposed in two opposite positions and these two positions are indicated by indicia on the knob H6 which, in the present instance, consists of the letters P and S, indicative of print and skip operations as brought about by the selector mechanism. In the present instance the'knob I I6 is so positioned that the letter S is in upper position and the selector mechanism is arranged to effect skip operation.

It has been pointed out that until the bar 94 is stopped, the pivotal mountings SI and its have their centers coincident and therefore the position of the link its is fixed. Thus, when the eccentric pin I I5 is turned the bell crank I I2 will be moved by reason of the mounting of the pin in the arm II4 thereof and the fixed position of the link I98. On the arm II! of the bell crank H2 is a head II8 having notches H9 and I20 therein'providing a nose I2! therebetween, the head I I8 having shoulders I22 and I23 thereon at the outer ends of the notches IIS and I20, respectively.

When the parts are located by the depicted disposition of the pin II5 the bell crank H2 is positicned as shown in Fig. 6 and the dog I24 is disposed in the notch H9. The dog I24 is carried by the yieldable arm I25 fixed to the rocker I26 pivotally mounted on the bracket H9 at I21. Pivotally mounted at I28 on the bracket I Iii'is a rocker I29 including arms ISt and I3I. At the outer end of the arm I3I a rod I92 is pivotally connected that extends through a bore in the boss I33 on the sleeve I8. A collar I34 is adjustably mounted on the rod I32 and is held against the upper face of the boss I33 by the spring I35 extended between spring anchors on the rocker I29 and the bracket III When the rocker I9 moves upwardly the rod 1321s moved upwardly and the arm I 3! of the rocker I29 also moves upwardly. On the rocker I29 is an arm I39 having a plate I3'I' secured thereto including a. nose I37. In the rocker I26 there is a recess I38 providing a nose I39.

As has been described, at the time the casting 99 moves the selector bar 94 toward the printing device IE5, the coincidence of the centers of the mountings 9i and I99 is altered, if the tabs on the printing device I95 engage pins 93 and interrupt movement of the selector bar S4, and this moves the link I98 downwardly. When the link I98 so moves the arm II? of the bell crank II2 the dog I24 is unseated from the notch H9 and the nose thereof seats on the nose I2 I. When the rocker I9 was moved upwardly the rocker I29 was motivated, as describcd,'and therefore the arm S36 moved into a position substantially similar to that shown in Fig. '7. The parts then assume positions such that the plate IS'I extends into the recess I38, as shown in Fig. 7, and the shoulder I3'I may then engage the shoulder I39 to lock the parts in position. t the time the arm I3I moved upwardly the arm I39 of the rocker I29 moved downwardly and at this time the pawl I] pivotally mounted at I4! on the disc I42 fixed on the shaft III was in a position slightly forward of that illustrated in Fig. 7. When the shoulders I3'I and I39 are engaged in the justdescribed manner the arm I39 will be retained in this position and the end thereof will engage the end of the pawl I40 and will pivot the same against the action of the spring I43 and thus the nose of the pawl will disengage the shoulder I44 on the sleeve I00.

When the nose of the pawl I49 engages the lug I44, the sleeve I90 is driven with the shaft I4. Therefore when the pawl is disengaged from the shoulder the movement of the sleeve I90 will be interrupted and no movement will be imparted to theconjugatedcams 32 and 33 and therefore the platen P will not be operated. It is therefore manifest that a printing device with tabs thereon in accordance with the location of the pins 93 wiil render the platen inoperative when the knob I I6 is disposed as shown in Fig. '7 and thus the printing device will be, as it is termed, skipped.

In the foregoing description I have set forth the operation of the device when it is arranged to skip a printing device having tabs thereon in predetermined positions. However it is often desirable to print such printing devices rather than skip them and when this is desired the knob H6 is turned to position the letter P in upright position. Thus, when the centers 9! and I93 are coincident the bell crank I I2 will be so positioned that the nose of the dog I24 will be disposed on the shoulder I22. Thus, when the casting 99 is moved in the manner described and movement of the selector bar therewith is interrupted by the engagement of the pins 98 with tabs T on the printing device I95 the center of the pivotal mounting I39 is moved from coincidence with the center SI and the bell crank H2 is so moved that the dog I24 seats in the notch H9 and thus the rocker I26 is positioned substantially as shown in Fig. 6. Therefore, when the rocker I29 is moved the plate carrying the portion I31 will not be positioned in the recess I38 and therefore the rocker I29 will not be locked in its lower position and thus the end of the arm I39 will not be in the path of movement of the pawl I48 and the inter-connection of the shaft I4 and the sleeve IIlIl through the disc I42, pawl I49, and shoulder I44 will not be interrupted and therefore the conjugated cams 82 and 33 will be operated to bring about a printing operation of the platen. However, when the tabs T on the printing device I95 are not in the predetermined positions the coincidence of the centers of the pivotal mountings 9| and I09 is not altered and because the nose of the dog I24 is resting on the shoulder I22 the rocker I 26 remains positioned in its upper position, and therefore when the rocker I29 is moved, the plate I31 enters the recess I38 and the shoulders I3! and I39 are engaged and thus the parts are locked in position so that the interconnection of the shaft 14 and the sleeve I99 is interrupted and therefore printing devices not tabbed in the predetermined manner willbe skipped.

It has been pointed out that the printing device I05 is in selecting position and that the printing device I96 is in printing position. Moreover, it is apparent that the operation of the platen is determined from the printing device I05. Therefore. immediately following the determination of the selection the rocker I9 will be moved 'to impart a driving movement to the sprocket 25 and the chain 85 will therefore be motivated and the printing device I95 will be moved into the position of the printing device I99 and it is from the printing device I06 that the impression is made by the platen P. Y

In my co-pending application, Serial No.

497,439, filed in the United States Patent Ofiice on November 22, 1930, I have described howa tax bill or other sheet to be printed is moved into printing positiongandtherein it is set forth that'such bills often have more than one section and that impressions are'made from eachfprinti-ng device on each section of the bill, when the selector determines that the printing device is 'tobe used in a printing operation.- Moreover, anna referred to application I have described how the machine is arranged to determine whether one, two or threeimpressions are to be made on thebill, and as pointed outtherein this is related to the relative rotation of the cam shaft H with respect to the rotation of the platen operating shaft It. If, for example, a two-section tax bill is to be printed two impressions will be made from the printing device in printing position and under such conditions the cam shaft II makes one revolution-to two of the platen operating shaft. When twoor more impressions are to be made from each printing device the selecting and the printing device feeding means are rendered inoperative on all save, the last printing operation, and to accomplish this the following mechanism are provided: On the cam shaft II is a cam I45 (Fig. 6) engaged byaroller I45 on the arm M'Iof the rocker I40 pivotally mounted-at I40 on the lug I50 carried by the bed 21. The rocker .I48includes an arm I5! having a cam surface I52 thereon. On

the latch 3'! there is a pinI 53 and when the rise on the cam I engages the roller I46,-the arm I41 of the rocker I 48 is pivoted downwardly which pivots the arm I5I of said rocker upwardly, and the cam surface I52 thereon engages'the pin .I53 and disengages the shoulder 88 from the collar I6 by pivoting the latch 81 about the pivotal mounting ing any movement to the rocker I9. However,

during the time the last impressions arebeing made from the printing device I06 the rise on the cam I45 willdisengage the roller I46 and therefore the cam surface I52 will move from engagement with the pin I53 and the shoulder 88 will again engage the collar I6 and therefore the rocker I9 and consequently the detecting portions of the selector mechanism will be rendered operative", and thus a selection will be made from the printing device I05. Further, the printing device feedwill be rendered operative. I It has been pointed out, however, that in the printing of tax bills and thelike the printing devicesare often arranged in groups consisting of lead. and follower devices. In the disclosed arrangement the selection is made from the lead printing devices, not from follower printing devices, andlitis'therefore manifest that if the selector be rendered operative immediately after impressions have been made from a lead printing device the selector mechanisms would operate on follower printing devices if there are any. This, however, is avoided by providing the following arrangement: 7

The follower printing devices will have a tab T (Fig. 5) or other identifying means positioned thereon in a certain definite location to engagea pin I54 and cause engagement of the contacts I55 and I56 to close an electric circuit to; the

' solenoid I51 at a determined time in the operacam shaft II Current will be supplied from the line Wires I99 and 200, (Fig. 5a) connected to conductors 2M and 202 by the switch 203, the conductors 20I and 202 being directed to a mo-, tor 204' which is the source of power heretofore referred to. Conductors 205 and 200 are respectively connected to the conductors'ZIiI and 202, and to conductors 201 and 203. by the-switch 209. When the switch 203 is open, operation of the machine is prevented and'opening of the switch prevents operation of the electrical portions of the selector. Thus, when both the switches and 209 are closed and the contacts I55 and I55 and the switch I95 is closed, the solenoid I51 will be energized in the following manner: Current will flow from the conductor I99 to the conductor 20 I, through conductor 205, conductor 201, contact I55, contact I53, conductor 2I0, winding of the solenoid I 51, conductor 2! I, switch I95, conductor 2 I2, conductor 208, conductor 200, conductor 202, toconductor 2%. .The solenoid I5? eludes an armature I58 extended through an opening.I50."(Fig. 6) in the bracket III) and includesa pointed end I50. On the rocker I 26 there is'an T-shaped plate IBi embodying an upwardly extending portion having a knife edge I52 thereon. It has been described how the rocker IZfiis disposed in a certain positionby the selector and once the rocker has been set it is held in the determined position until another selection is performed. The knife edge IE2 is aligned with and arranged adjacent to the opening I60 and when the rocker is positioned this knife edge is disposed on one side or the other of the center of the opening I60. Therefore, when the solenoid I5? is energized the armaturev I58 moves to dispose the pointed end I59 thereof in the path of theknife edge I62, and therefore the rocker I25 will be retained in position by the engagement of these edges. Thus, when the follower devices move into selecting position after a lead device has been in this posi-. tion and determined the setting of the rocker I26, said rocker will be held in this position until another lead device moves into selecting position, for each follower device will be equipped with a tab T that will bring about the closing of the contacts I55 and I55, but no such tab is provided on the lead devices.

In the foregoing description I have pointed out that the operation of the shaft I4 and the cam shaft 'II should be timed relation but this might be more accurately stated in that it is the operation of the sleeve I00 and the shaft II which is in timed relation as the shaft 14 rotates constantly when the machine is operated. I have set forth that the sleeve I00 is disconnected from the shaft I4 when no printing operation is tobe performed by the platen and when this occurs it is necessary that operation of the cam shaft be interrupted so that the timed relation may be maintained. Moreover, it has been described thatthe disconnecting of the sleeve from the shaft is, brought about by positioning the arm I30 of the rocker I20 in a determined position. I I have therefore provided an arrangement operable from the rocker I 29 for interrupting movement of the cam shaft II when a printing device-is to be skipped and this includes the following devices: Connected to the rocker I 29 is a bar I56 (Fig. 2) whichhas a depending lug I5? at one end thereof onwhich there is a roller I58. Suitably. supported on the bracket 28 is a rocker I69 carrying a roller I70 engageable by the roller I08. When the roller I68 engages the roller I'm the tongue IIl (Fig. 2) carried by the rocker H69 is moved into the path of the pawl 512, the nose of which normally rests in the pocket 13 on the collar I14 fixed on the shaft 32. The pawl H2 is carried by the gear 35'of the clutch 34. Therefore, when, in the rotation of the clutch structure with the shaft 32, the end of the pawl H2 engages the end ofthe tongue I'II,

. after the same has been positioned as above described, the nose of the pawl is retracted from the pocket H3 and thus the plate I73 is discone nected from the shaft 32 and therefore rotation of the gear 35 is interrupted. It has been previously described how the gear 35 meshes with the geartn and how other devices, including the speed changing mechanism, previously described, are operable from the gear 35 to bring about operation of the cam shaft 7!. Therefore, movement of the camshaft will be interrupted when the pawl I is disconnected as described.

In my c-o-pending application, Serial No. 491%39, filed in the United States Patent Ofiice on November 22, l930,-and in my co-pending application, Serial No. 497,440, filed in the United States Patent Ofiice on November 22, 1930, I have described how the sheet feeding means I15 is operated'from a shaft lit by the pinion 43 through an intermediategear I I! which meshes with a gear I13 fixed on the shaft I16. On the shaft H6 there is a disc I19 (Fig. 1a) engageable by brake shoes Hit and IBI and these brake shoes are engaged with the disc by a lever I82 pivotally mounted at I83 and operable by the electrical relay we in the following manner:

On the shaft 32 there is a cam I85 (Fig. 2) and fixed on the housing of the clutch 34 is a 7 switch I85 having a plunger I81 that is engaged by the rise on the cam I during each' revolution of the shaft 32 whereby the switch is closed upon each revolution. A circuit, however, is not closed by the'switch I85 unless the contacts I63 and 594 (Fig. 6) have been engaged, this being brought about by the adjustable member I65 on the arm I3I of the rocker I29. The contacts I63 and I 54 will be engaged only when the arm I3I is in the uppermost position (Fig. '7), for the arm is so located when rotation of the cam shaft 1| is interrupted, for it is such positioning of the arm that causes interruption ofthe cam movement. Therefore, if the switches 203 and 2&9 are closed the relay I84 will be energized in the following manner:

Current will flow from the line wire I99 through conductor 26! {conductor 205, conductor 2G1, conductor 2E3, contact I63, contact I54, conductor 2%, through the winding of the relay I84, conductor 5255, switch I85, conductor 2I6, conductor 238, conductor 236, conductor 202, to line wire 28%. When the relay I84 is so energized the armature 533 thereof is attracted and as this armature is connected to the lever. I32 said lever will be moved to momentarily engage the brake shoes with the disc and thus arrest rotation of the shaft Ht. Thus, rotation of the cam shaft II is instantly arrested when the arm I3I is in its uppermost position and the arm I30 will therefore cause disengagement of the pawl I40 from the shoulder-I44. Moreover, movement .of the sleeve ms is also arrested and it is manifest that the timed relation will be maintained, for the mechanisms are so constructed that the clutch will be reengaged at atime in'the cycle of operation relative to the time at which the pawl its reengages the shoulder I44. The sheet feeding device I15 is also stopped along with the cam shaft It is sometimes desirable that a certain group of printing devices be printed and often this group is tabbed in a manner substantially similar to another group with the exception that an additional tab will be provided on the devices of one group that is not provided on the other group or a switch tab may be provided that can be set in different positions to divide the printing devices into groups. To segregate such a group of printing devices a pin of greater length than the pins 98 heretofore described will be arranged in a position to correspond with the position of the tab defining the group. Therefore, if the selector is set to print devices tabbed in a certain manner the bell crank II 2 will be positioned to dispose the nose of the dog I24 on the shoulder I22 and when ordinary length pins bring about the operation the dog seats in the notch I I9, but when the longer pin brings about the operation the bell crank II2 will be moved in an amount greater than it is ordinarily moved and therefore instead of the dog I24 seating in the notch II9 the nose thereof will engage the nose I22 and thus operation opposite to that ordinarily brought about will occur. When the mechanism is set in skip position the dog I24 is normally disposed in the notch I I9 and moves onto the projection I2I when a printing device is to be skippedas is determined by ordinary length pins. But, when a longer pin engages a tab the dog I24 will move out of the notch I I9 but instead of seating on the nose IZI it will seat in the notch I28, and here again operation opposite to that brought about by the ordinary length pins will occur.

It is often desirable to operate the machine repetitiously as during testing of the machine or at other times and this is accomplished in the following manner: Extending downwardly from the housing III is a rod I88 connected at I99 to the arm I5! and having a knob i9I slidably connected thereto at the upper end thereof. On the knob I9I is: a pin I92. The knob MI is rotatable also on the rod I89 and when raised and turned into one position it may be aligned with the restricted opening I93 in the housing I I I and when in this position the rod I89 is held in an upper position to so locate the cam surface I52 that the pin I53 will be engaged thereby for the purpose described heretofore, but when the knob is rotated to align the pin with the enlarged opening I94 the rod I89 is lowered and the arm I5I may operate in an unhampered manner because of the slidable connection between the rod I89 and the knob I9 I The operation of the device is as follows: The printing devices are introduced into the magazine and are withdrawn therefrom and are sequentially passed through the guideway 85 first through selecting and then into printing position after which the devices are discharged into a suitable galley. If the printing device which moves into selecting position is tabbed in accordance with the group it is desired to print, and the knob I It is set with the indicia P in upper most position, the operation will be as follows: At the start of a cycle of operation the dog I24 will rest on the periphery of the arm II! at the point I22. If the machine is put into operation without feeding printing devices or without any printing devices passing the selector bar and as long as a pin in the selector bar does not contact the tab, no rela tive motion will be imparted to the arm I I7. Consequently, the dog I25 will remain at point I22 thereby holding the rocker I26 in its uppermost positio-n'so that the nose I 31 on rocker I29 will engage the nose' I39 and rocker I29 will be latched in its upper position. It is to be understood that the rocker IE9 is turning in a clockwise direction as viewed in Fig. 6 during the time that the selector bar is being depressed by roller 93 on the rocker I9. The pawl I49 has been previously disengaged by the arm I39 so that the sleeve I99 is not turning and also the cam shaft I I is stationary due to the position of the rocker I29 and cooperating parts. The roller I46 on arm I41 will be resting on the-low part of cam I45. It will be noticed from this that when the selector parts are set to cause a printing device to be skipped the roller I49 will rest on the-low part of the cam 545 so that the machine will feed printing devices consecutively and will not duplicate until shaft I I is again turning. r

When the printing devices start through the machine the nose I37 will remain seated against shoulder I39 until a pin on the selector bar strikes.

a tab. During every operation of the arm I9, or when arm I9 reaches the limitof its clockwise ro tation, the rod I32 is lifted and the rocker I29 is rotated a suflicient amount so that the nose I32 will be cleared slightly from the'nose I39 thereby permitting the freepositioning of the pawl I26. On the beginningof the next cycle and when a printing device tabbed to correspond to the desired group is in the selecting osition and underpletes its motion. Therefore, theroller 93 (Fig,

5) engaging the bar 92 will always rotate casting 90 to a fixed position and consequently from the time that the pin 98 strikes a tab a relative motion of the selector bar 94 to the casting 90 will be set up and which movement will be in a counterclockwise'direction. This motion will be imparted through link I98 connected to the arm I01 on the selector bar 94 and at the other end to rocker I I I at I I5.' If the pin 98 striking atab is of the regular length the motion set up by its striking a tab will be just sufficient to rotate rocker III a suf ficient amount that notch I I9 will position itself under the dog I24. This occurs just at the time that the rocker I9 hascompleted the limit of its motion in a clockwise direction and the relative position of the parts nowis as follows;

'Ihedog I24 willbe resting innotch I I9 as shown in Fig. 6. Rocker I29 will-have reached the limit of its clockwise rotation positioning nose I31 as shown in 7 to permit free action of pawl I26. As the machine now continues to rotate, the rocker I29 will commence to rotate in a counterclockwise direction much more rapidly than the lifting of the selector bar. Consequently, dog l24will rest in its position a sufficient length of time so that blade it? will travel past shoulder I39 and latching up ofarm I29 is prevented and at the end of the cycle the relative positioning of the parts will be as follows: The selector bar will be in itsupper position with dog'I24 again resting-at I22, nose 531 not having latched up permits rocker I29 to rotate the limit of its counterclockwise rotation lifting arm I clear so that pawl I46 which about at this time arrives in the position shown in Fig. 6 permits it to engage shoulder I44 to pickup the sleeve which operates the stamper'arm and also the other mechanism as described.

The foregoing operation is brought about by a lead printing device and if one lead printing device is followed by another and the second device is to be printed as above described, the foregoing operation will be repeated. However, if one or more follower plates are behind the leadprinting device the solenoid I 53' will be energized inthe manner described and will hold the selector mechanism in the setting determined by the lead plate and this setting will be maintained until another lead plate moves into selecting position.

If the indicia S is in upper position whereby printing devices tabbed in a certain way are to be skipped, then the nose I26 will normally be positioned in notch II9 instead of resting at I22 and when the pins in the selector bar engage tabs corresponding to the set-up of the pins, the nose I24 will seat on point IEI thereby causing a latching up of the blade 31 on the shoulder I39 which causes arm I39 to engage pawl I40 whereby the pawl will disengage the shoulder I44 and the platen arm-will not be operated and hence the printing device will be fed through the machine without an impression being taken therefrom. When this occurs, rotation ofthe cam shaft 'II is alsoarrested and this cam shaft will not again be rotated until the nose. I38 has been released from the nose I39 and when movement of the cam shaft is arrested the cam 145 will be in the 1 position illustrated in Fig. 6 whereby the printing device moving means will continue to operate and this operation will continue until a printing device not tabbed in the determined manner moves to selecting position whereupon the nose I24 will remain in the notch H9 and hence the pawl I49 will not be disengaged from the shoulder I44 and respects but which have the operation thereof timed, and I have shown how this selector may be used to interrupt operation of such parts without altering the timed relation thereof. Furthermore, the selector described herein is one which will operate either successively on printing devices passed in the machine or one which may be arranged to operate only on certain of the printing devices sequentially passing through the machine wherein such printing devices are arranged in groups embodying lead and follower printing devices. Moreover, the selector is so arranged that an operation opposite to that for which it is set may be readily brought about by merely varying the length of one of the detecting members.

In the foregoing description I have set forth a means for sequentially moving lead and follower pinting devices past the printing means, a selecetor for determining the operation of said printing means, and detecting means including a part cooperating with the lead printing devices to determine the set-up of said selector and another part cooperating with the follower printing devices to maintain the set-up of said selector.
